I was wondering if someone could give me a direct answer because i cant seem to find one sifting through the forums.
I originally rooted with root master back when i got the phone. it is still on mje/4.3 stock build. things look a little more complicated then i remember, since my phone hasn't seen an update in over 3 years. I originally froze the verizon ota updates with tibackup, along with all the other bloatware.
My main questions are:
1. I would like to get a 6.0 Rom that looks like the note 7 did, can i do it all with odin and just flash a bunch of files?
2. Do I need a custom recovery like twrp or cwm?
3. I've read about an activation lock but can't find it in my menus, did it not exist yet on 4.3?
If anyone can point me in the right direction I would appreciate it, I really dont wanna brick my phone.
I'm still on MJE firmware, but using an older CM13 (temasek) ROM. So it's marshmallow but no Touchwiz or other Samsung add-ons.
Here are the MJE-specific issues:
1) You can't boot N* or O* stock kernels because of differences in the way that DTB (device tree blobs) are packed into the boot image. I've played with re-packing the boot images, but the kernels seem to run off into the weeds after a few tens of seconds.
2) TowelRoot works on MI9 through NC2(leak) but I think not thereafter - if you wanted to avoid a bootloader firmware upgrade but re-flash via Odin the MJE firmware for "starting from scratch" purposes, you have a means to re-root that does not require a PC.
3) If you retain the MJE bootloader, use the TWRP (hltevzw) -4.3 recovery; the -4.4 recovery will not boot, presumably due to issues similar to (1) above.
4) Not specific to MJE - but important - is the fact that if you want to boot either a custom kernel or custom recovery, you need to unlock your bootloader first. You can unlock your bootloader from any rooted ROM, but be aware that flashing stock firmware with Odin thereafter will re-lock the bootloader.
If you were to "start from scratch" but upgrade to more recent stock software before rooting, be aware that there is no publicly available root for NC4 or NK1; you would need to install stock OB6 or OF1, and follow that by using those "yemen" rooting tools. (Are they safe to use? I don't know frankly)
I am assuming that the N* and O* series bootloaders are backwards compatible with regard to device tree booting issues (see #1 above), because the temasek CM13 roms (having a custom kernel) boot on both OF1- and (my) MJE- bootloader phone. I guess that means it uses a "4.3" DTB packing in the boot image.
You are probably going to want to use TiBu to make important backups, and also copy everything off the phone that is important to you. You should assume that if anything goes wrong, an Odin re-install and factory reset are in the device's future.
Having said all this, I'm not sure there is such a thing as a ROM which "looks like Note7" - this is an old phone with almost no ROM developers left. There might have been more, but the bootloader unlock was achieved 2+ years after the phone's release, and most of the active developers moved on to new phones before that happened.
good luck
I had 6p since release. I didn't want to root while still getting OTA updates. I figured Oreo may be last I will get so I rooted with Skipsoft Toolkit and all went well. Now onto Roms. My main question is, can I flash any ROM regardless of the Android version? As I'm on Oreo, can I flash Pure Nexus running 7.1.2, or must I only flash Oreo Roms?
It's more the custom recovery u need than being rooted.
If your bootloader is unlocked and you got TWRP as recovery installed u can flash any custom rom u want to.
If you like to stay up to date with security patches you should flash Oreo roms in the future.

It's inadvisable to jump to a custom ROM based on a different version of Android. So, if you were on stock Oreo and you wanted to flash a custom Nougat ROM, you'd be better to revert to the factory Nougat images and then flash an N-based ROM. Regardless of what you try though, make sure you have the latest TWRP and have a full backup (also referred to as a Nandroid backup) before you flash any modifications. If you end up borking things then you can simply restore your device to it's last stable state.
When it comes to rooting, recoveries and flashing ROMs, I'd highly recommend you become familiar with, and follow, the guide at https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928 as it's very clear to how you do most modifications to your device.
Happy flashing.

Thanks for that link. I thought I knew what I was doing, but I see I already screwed up, because I installed TWRP and rooted. Set phone the way I wanted and made a Nandroid. I never made a Nandroid of my stock Oreo set up. Damn. Hope that doesn't come back to bite me.

As long as the setup is working and mostly the way you want it, that's what you want the nandroid for. Most people will just ensure they have a working ROM for a backup before they begin flashing other stuff. I'd also recommend moving a copy to your computer. If you ever do a 'complete' wipe that includes your sd card, your backups will be gone too.
The one thing to be aware of with nandroid backups is, if you have any kind of screen PIN/security, when you restore it, you're temporarily locked out as the PIN doesn't work. If this happens to you, it's not the end of the world, but you have to boot into TWRP, go into your system files and delete the three lockscreen db files, then you'll effectively have an unlocked screen and can reset your PIN, pattern and fingerprint. The easiest thing to do (which I never remember) is to remove lockscreen security before you make the backup.
Hi, i just got the moto g5 plus, i always have phones that from the moment i bought them they wouldn recive any updates, so i realy didnt care if unlocking the bootloader installing new recoverys will affect the OTA updates. So i have a couple of questions.
1- first i want to at least have a stock firmware just in case, but i cant figure out which one should i download from here
firmware.center/firmware/Motorola/Moto%20G5%20Plus/Stock/
Before i always use sammobile.com and it was really easy to found a stock firmware from Argentina. My compilation number is: npns25.137-15-11 this means that i suppose to download that one XT1681-XT1683_POTTER_BRASIL_LATAM_MEXICO_7.0_NPN25.137-15_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip ?
2- it is possible to unlock the bootloader and root your phone without installing a new recovery? i was reading some post and when you change your recovery or you modify something the OTA update will stop working. they are some methods like the magisk but they seem i little bit too complex for me and i don't want to do it every time that a new update is available.
thanks for the help, and sorry for my English i am from Argentina.
1. yes, but any build will flash and run, so it doesn't really matter that much...
2. Nope. You need to flash TWRP in order to root. This is because the stock recovery will only flash signed images... You can use Magisk, after backing up a stock build. Anytime there is an OTA, just restore to that system image, Flash the original recovery via fastboot, and then take the OTA. Once you have it, flash TWRP again, and restore to your other build. Or just run a custom room like Lineage or RR, and this whole thing isn't really an issue anymore.

yeah i know i had a samsung galaxy s3 until now, and i always have cyanogen, slimrom or now lineage, but this is the first device that i have one that will get updates (at least 1 more :S) and i want to seize that
i will start downloading that file just in case
1- ok so unlocking the bootloader doesn't affect updates only when you modify files? when the update is installing is basically comparing the files that you have with the ones that you suppose to have and if there is something different it will fail? its something like that?
2-dumb question how do you do a full backup in the stock recovery there is no option no do a nandroid backup or it will appear after i just unlock the bootloader?
I am not responsible for your bricked phone or pigeon poo on your toupe. Do at your own risk.
Many thanks to @SupahCookie for idea and motivation!
INTENTIONALLY DOES --NOT-- LOCK BOOTLOADER!!!
Get factory images here:
https://forum.xda-developers.com/mo...ock-images-t3736767/post75236696#post75236696
THIS GUIDE IS FOR FACTORY/STOCK ROMs - NOT YOUR AVERAGE CUSTOM ROM which may not have bootloaders!!! (thanks!!!!! @echo92 )
FIX:
IF YOU ARE ABLE TO GET TO FASTBOOT THIS SHOULD WORK.
IF YOU HAVE 8.x bootloaders AND ARE DOWNGRADING TO 7, use "Alternative to RSDlite" below.
1 boot to win - 7 or 10 works fine.
2 boot phone to fastboot, and connect phone to computer.
3 start RSDlite
pick a ROM. I believe I used a 7.1.1 rom
3Nov9-ADDISON_NPNS26.118-22-2-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
RSDlite installed it and fixed the problem.
- -
I was then able to use RSDlite to install @rafikowy 's signed 8.0 . - going up from 7 to 8.
- -
- -
If you are on 8.x bootloaders and want to go to 7.x bootloaders, use this (RSDlite throws an error and stops):
ALTERNATIVE TO RSDlite:
1 I used 7zip to extract that 7.1.1 zip (or any ROM zip) into a folder x,
2 add all the adb and fastboot junk to folder x,
3 add the attached file (rename it to flash.bat) to folder x.
4 boot phone to fastboot and connect to computer.
5 click on flash.bat - it throws a lot of "slot" errors but works just fine.
6 reboot your phone if it hasn't already and go through the 7.x install stuffs.
7 you will not show an IMEI if you are coming from an 8.x bootloader. However, it IS there.
NOTE: you may need to add a line to the flash.bat if there are more/less sparsechunk's in your FACTORY/STOCK ROM...
THIS IS NOT FOR CUSTOM ROMs!!!!!!!
EDIT: 3-8-19: I just did this myself to go back very briefly to 7.1 - be sure you don't flash TWRP to it if your going to take OTAs - it will brick it. boot to TWRP if you need TWRP briefly: fastboot boot twrpimg.img
----------
If you can boot to fastboot screen, you can do anything.
Never OTA a ROM if you have modified recovery (TWRP, etc) or if magisk is present.
https://forum.xda-developers.com/mo...p-flashing-t3813498/post77011495#post77011495
I changed the attached file to add pause and reboot and exit to make it slightly more automated.
I have successfully used this many times going back and forth. If you can boot to fastboot screen, you can save your phone and flash anything you want.
You may wish to advise users that if they downgrade to Nougat not to use Nougat OTA updates. The reason being that a downgraded stock Oreo device may still have the Oreo bootloader on it. Thus, attempting to use Nougat OTA updates may hard brick their device (as the bootloader is likely corrupted, meaning no fastboot).
Users could either use the Feb 2018 NPN26.118-22-2-17 firmware from your link https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/ as that was the last Nougat firmware (and thus no Nougat OTA updates) or avoid using OTA updates whilst downgraded.

Interesting. I used the above GUIDE to go up and down a number of times on my phone (about 20 total) , installing and running on both 7 and 8, and then went down to a Nov 7.1.1 and let it ota all the way up to 8.0 and that is what I am using now. I found that when i used a factory zip, and the above procedure, it corrected the bootloaders to the appropriate version that i was flashing - either RSDlite or the more manual path which ignores the errors worked for me.
Using the above procedure , you get the correct bootloaders, which are in the zip.
Please correct me if i am wrong!

That's intriguing - we saw previously on Z Play that users downgrading their stock firmware (e.g. https://forum.xda-developers.com/moto-z-play/help/hard-brick-moto-z-play-patch-abril-t3782927 )and then using OTA updates hard bricked their device (hence the number of users asking for a blankflash, as fastboot no longer works). I don't know if these users hard bricked by downgrading their firmware too far and then flashed an OTA radically different to their previous firmware, or whether it's a risk that's taken by any downgrading of firmware.
When you used fastboot, did you see any 'security downgrade errors' when you flashed the bootloader, and is your bootloader version now C180, as you've flashed the Oreo OTA?

YES - that's why I wrote these 3 guides - before, it was quite possible to wind up with a bootloader mix - esp depending on the zip you use! - factory/stock only!!!
I added a line to the guide saying that it is only intended to be used for the factory/stock zips as these have (I believe) the bootloaders appropriate to the ROM.
Many thanks for pursuing this! - I wonder if we'll have to exclude certain ROMs that are in the factory lists?????

If you have TWRP (or I assume any custom recovery) present when you try to ota, it can download just fine and then reboot to the update. I had TWRP and wound up in a situation where my phone would only boot to twrp no matter what I flashed or restored. I booted phone to fastboot, RSDlite'ed that 11-09-17 factory zip and all was well. In that particular case I did not fully install 7.x but immediately RSDlite'ed rafikowy's 8.0 signed stock and went on with my testing. Since then I always boot to TWRP rather than intalling it and do my thing. (thanks @jceballos )

Sorry - since it throws a million errors I never look at it if it works.
The particular build I am on at the moment - is BL: C1.82
This one started from that Nov '17 build and ota'ed all the way to 8.0 Apr.
I root and unroot as needed per rafikowy's method but using a boot to TWRP - never an install TWRP.
I'll put up a new guide ref ota and recovery and brick.

1) If you have TWRP, then using an OTA will fail - as you've not got stock recovery (and likely other modifications, including possibly a system partition set to read-write status). As you noted, having TWRP seems to cause a bootloop when rebooting - I'm not sure if the OTA sets a boot flag to stay in recovery until the update is completed. For the G4/Plus, there's a possible solution by wiping the misc partition but I don't know if there's a similar partition for Z Play devices: https://forum.xda-developers.com/moto-g4/help/troubleshooting-twrp-boot-loop-ota-t3714325
The only other solution I've seen is a clean flash of the stock ROM to get your device booting properly.
Booting to TWRP rather than flashing would mean your stock recovery is still present on your device. The only downside is if you need to make modifications, you'd need your computer to boot to TWRP.
2)BL C1.82 seems to be the bootloader provided by the Oreo April 2018 security patch update, so your device looks to be on the right bootloader. It's still curious that the Nov 2017 firmware worked whereas countless other 'factory' stock ROMs caused hard bricks when downgraded to and then OTA updates were installed.
As you mentioned, custom ROMs don't have bootloaders and thus don't care about your bootloader version usually (though I've seen some ROMs require a certain bootloader). However, stock ROMs and stock OTA updates do have bootloaders, which is why downgrading can be risky.

Downgrading is a piece of cake if you don't use RSDlite - it throws an error and stops. Using the bat file it can happily throw all the errors it wants and all I care is at the end I have what I want.
It does indeed change the entire environment when you bat file the zip contents. You can bat file to get from 8 to 7 and then use RSDlite to flash a different 7 OR 8 zip file. There is no resulting difference in whether you RSDlite it or bat file it - the bat file simply comes from the .xml file that is within the zip. There is very little or no difference between that among addison factory/stock zips. Other zips are different (custom ROMs.)
Grab any factory/stock zip for addison and expand it and you will see modems, bootloaders, indeed absolutely everything you would find on that phone if you went to a store and bought it. SupahCookie simply added a couple lock command lines because it was intended for folks who somehow thought that if phone was locked they could take it back to the store and get their money back. Or some such. I found that ATT folk didn't care if you were on CM or whatever if you just needed to swap SIMs or whatever.
I DON'T want to lock the phone as it prevents me from modifying forever. Oh yeah that reminds me I was going to post the obligatory guide (again) about how to flash a white boot logo so you don't get that message - it's still there LOL but since the font is in white, you can't see it.
I have a Moto Z2 Play and used this to get out of a rather sticky situation.. My IEMI shows 0 now and I'm curious if there's a way to fix this? Also, You say you've done OTA updates? My phone is telling my I have some, is it safe to try?

Thanks for feedback and great on success.
IMEI will show zero if using oreo, It will show again if using N. Remember that if you go from O to N you need to use the "Alternative to RSD" as RSD will simply throw an error and stop.
If you have TWRP and/or Magisk you must get rid of them before ota - if twrp present you will soft brick and have to do alternative again - flash a stock recovery. Simply uninstalling/flash magisk will probably not be enough - it will likely d/l but error part way through update. If you are sitting on rafikowy's stock oreo, and haven't modified it, you should be fine. I know Apr and June are out there. I flashed his stock 8.0 and took June fine. Z2 should be no different though of course I can't guarantee it
If you have success, let us know what you have done so others looking in will know. Thanks!

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

Custom ROMs won't usually update the bootloader (even if they are newer) as stock ROMs typically only have the bootloader firmware.
You could look into flashing the stock Oreo albus 8.0 ROM https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-oreo-retail-via-fastboot-t3786153 or the 8.0 June 2018 firmware https://forum.xda-developers.com/z2-play/how-to/fastboot-rom-albusretail8-0-0opss27-76-t3822195 but please check that firmware has been released for your device variant.
I don't know if updating your baseband to stock Oreo formally may fix your IMEI issue.

It had 7.1.1 stock. I rooted it, and then flashed Resurrection Remix (which was yes 8.1 I believe) and the upgraded bootloader. I then found out my service wouldn't work with that.. so I attempted to flash back to stock which gave me a flurry of issues.. eventually getting to nothing but fastboot working. Flashed back to working with your guide to 7.1.1
If it helps in in fastboot it tells me BL: C0.CD

"BL: C0.CD" even right after flashing that albus 7.1.1 using "alternative" above?
What happens if you flash one of the oreo roms from the links I gave you above?
Yeah, RR wouldn't change bootloaders... so you upgraded bootloaders independendently?- that could easily lead to a soft brick... -
I read RR on Z2 and it says nothing about bootloaders even though it says 8.1 based, so i wonder if it needs 7.x bootloaders? I did not read entire thread...
In a reverse, I would wonder if you put an 8 on there if you wouldn't see your IMEI. (On the Z if you flash 8 You won't see the IMEI until you return to 7.)(wondering if z2 is reversed)

Yes, right after flashing that is the BL that fastboot is showing me. I don't recall updating the bootloader so to speak, however RR did require an updated variant of twrp which I flashed 3.2.2 I believe to get (unsure if that would have changed the bootloader or not). I also tried flashing a stock Oreo (which you've stated stock Roms usually only have the bootloaders so maybe somewhere during this process I updated it?). I wish I had all the notes for what I did to give more precise information, but I'm in a position where I really need my phone so I kinda just panicked and started flashing things when my service wouldn't work.
I'm highly considering trying to run an OTA (though very afraid of bricking). - On a side note though, it wouldn't even tell me I had OTA's until I did the steps in the original post here (doing the different 7.1.1. and 8.0 flashes, it wouldn't ever tell me I had updates, and now it does).
*** Edit ***
Looks like I'm able to enter stock recovery, which makes me believe everything is stock at the moment.

If you flashed a stock O that would have changed bl to O, but doing the above with the stock 7.1.1 would have changed them back to N. No matter (other than academic) that you don't remember the path - flashing a stock anything reverts it to that point in time. However, IMEI may have been moved - don't know. It will likely show on EITHER 7.x or 8.x stock - just don't know which.
If you flash a stock 8.x from those links I gave you above, it should offer you ota, ASSUMING there are any at this point in time(Z has 2). Adding Magisk at any point seems to hose you for receiving any more ota's - don't understand why, even with magisk uninstall, so that would mean going back to the latest stock and losing what you have (which is why I try to take a TBPro and copy that backup to PC (because re-flashing 8.x stock will likely reset internal storage.).
yes, if you enter stock recovery, you are likely at stock, though you could reflash the latest 7 or 8 stock to be sure, depending on which you want to use as base. Since 8 is having security fixes released, I choose 8 and will likely have no more interest (no time!) in 7.
So, ran the OTA and it was fine running the update and staying on N. I also downloaded the OTA for Oreo, when trying to update the recovery error'd out. It looked like the error said "Error in modem unexpected results" or something similar.

did it offer to let you d/l it again? you could try that.
However, there exist O stock zips in those links I gave you so you could just flash the latest...
What happens if I have lineage 15.1 and I want to return to 7.0 stock can I do it?
should I do a back up? I read that I could lose the imei :crying: how can I avoid it?
I would use this tutorial
https://www.youtube.com/watch?v=F_6LQr01GhY
thank you all for the help and advice :good::fingers-crossed:
sorry for my bad English
I don't know about lineage 15.1, but I had the OTA 8.1 update on my XT1644, and it broke my speakerphone and made my phone run like crap, so I just rolled back to stock 7.0 and am VERY happy.
I DID lose IMEI (I had IMEI=0), but from what I understand, it was because I manually flashed 7.0 from adb. I think that had I used the TWRP file, it wouldn't have happened.
I got IMEI back by following the directions in this thread:
https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-imei0-issue-t3859068
I also disabled OTA backups by doing this: https://forum.xda-developers.com/showpost.php?p=72373828&postcount=12
So that Motorola can't push an OTA on my phone and brick it.
You should make a complete backup following the directions of this thread:
https://forum.xda-developers.com/moto-g4-plus/how-to/guide-moto-g4-plus-complete-partition-t3875787
I know virtually nothing about messing with phones or Android. My motivation was that if I couldn't get rid of OTA 8.1, I was going to throw away my phone and get something different. And I didn't want to spend the money on a new phone. I figured I'd brick what I have, before I spent money on a new one.
I pretty much followed the directions on this thread:
https://forum.xda-developers.com/moto-g4-plus/how-to/guide-newbie-resource-thread-t3386584
Except that by loading 7.0 manually, it caused me to lose IMEI. Knowing what I know now, after flashing TWRP, I would have flashed 7.0 using TWRP. And I don't think I would have lost IMEI then.
Once I had 7.0 loaded, I flashed Magisk to get root.
Once I had root, I used a file explorer to go in and delete the app that pushes the OTA, so Motorola can't screw me. As far as I know, I am now permanently on 7.0.
Do this at your own risk. But you're already running Lineage, so I assume that you know way more about this than I do.
Edit: Just realized I kinda rambled here. So here's the condensed version of what I would do, I think... do at your own risk.
1. Use that thread I linked to back up your *everything*
2. Save stock 7.0 file, Elemental X file, and Magisk file on your SD card (all from XDA)
3. From TWRP, flash 7.0
4. Once you have 7.0, from TWRP flash Elemental X.
5. From TWRP, flash Magisk
6. From that link I posted, delete the file that stops OTA's.
I think you'll now be where I am, with rooted stock 7.0. But you should still have your IMEI. If you have IMEI=0, follow the directions in the link I posted.

I am eternally grateful for your help and message!! :good::good::good:
but in the tutorial that you sent me: https://forum.xda-developers.com/moto-g4-plus/how-to/guide-newbie-resource-thread-t3386584
indicate that the installation should be done manually by adb... do you think I should do it for TWRP ??

Flashing Stock Firmware:
1) Download the correct firmware for your device from http://www.filefactory.com/folder/c6cdedc45a775d27
2) Download adb and fastboot from https://drive.google.com/file/d/0B5j...ew?usp=sharing
3) Extract the firmware into the folder containing abd and fastboot.
4) Reboot the phone into Bootloader (power off, then press the power and volume down buttons simultaneously).
5) Execute these commands and make sure you receive an 'OKAY' after each command.

That tutorial was written years ago. I think back then, the only way was to manually install.
If you manually install 7.0, you will wipe your IMEI and have to restore it like I did.
I suggested the TWRP install because I *think* it wont wipe the IMEI.
If it does, you should still be able to recover it... but again, I barely know what I'm talking about. So please follow the thread about backing up your entire phone and persist, first. I am merely sharing with you what I did to roll back mine to 7.0, your experience may vary.
And again, if you do roll back, make sure you follow the instructions to disable OTA, because if you accidentally take an OTA, it will brick your phone for sure.
I literally just figured out how to do all this, this weekend. Prior to that I knew *nothing* about this stuff. So please read everything you can to educate yourself... its all here on this very good forum, you just have to piece it together. I am 100% a newbie.
